Contiguity Number Leasing Terms

Last modified February 7, 2026

These Number Leasing Terms ("Leasing Terms") supplement the Contiguity Services Agreement and apply when you lease phone numbers from Contiguity. By leasing a phone number, you agree to these Leasing Terms in addition to all other applicable terms.

1. Number Leasing Generally

1.1 What's Number Leasing

Leasing allows you to obtain and use phone numbers for communications purposes through Contiguity's Services. You do not own the numbers – you lease them from Contiguity for as long as you maintain an active lease and comply with these Terms.

1.2 Available Capabilities

Leased numbers can be used for the following capabilities, subject to availability and additional charges as described in Section 3:

(a) SMS + MMS — Send and receive text and multimedia messages (typically unlimited)

(b) Voice — Make and receive voice calls (typically billed based on usage)

(d) WhatsApp — Send and receive WhatsApp messages (typically unlimited)

Furthermore, some numbers may have additional features, including but not limited to, call forwarding, E911, and voicemail support.

Each capability may be added to a leased number as a separate add-on service with its own pricing and requirements. Unless otherwise specified, capabilities are provided on an unlimited basis. Voice and certain other capabilities may be billed based on actual usage.

1.3 No Ownership Rights

You do not own any leased numbers or any infrastructure, hardware, licenses, or systems used to provide number leasing services. All numbers remain the property of Contiguity or the underlying carriers. You receive only a limited, revocable license to use the number during the active lease period, subject to these Terms and all applicable carrier policies.

1.4 Carrier Dependency

All leased numbers are subject to the policies, requirements, and decisions of underlying telecommunications carriers (including but not limited to T-Mobile, AT&T, Verizon, and other carriers). Contiguity does not control carrier decisions and cannot guarantee:

(a) Number availability or assignment;

(b) Continued service or routing for any specific number;

(d) Protection from carrier filtering, blocking, or suspension; or

(e) Any particular level of service performance.

Carriers may change their policies, requirements, or treatment of numbers at any time, and such changes are beyond Contiguity's control.

2. Leasing Process

2.1 Number Selection and Assignment

You may request to lease a specific number (subject to availability) or allow Contiguity to assign an available number to you. Contiguity has sole discretion to approve or deny any number lease request and to assign numbers.

2.2 Number Provisioning

Once a number lease is approved, Contiguity will provision the number for your use. Provisioning times may vary based on number type, requested capabilities, carrier processing times, and other factors. Contiguity does not guarantee any specific provisioning timeline.

2.3 Activation Requirements

Before activating certain capabilities, you may be required to:

(a) Provide additional documentation or business information;

(b) Meet specific use case or eligibility requirements; and

3. Pricing and Billing

3.1 Base Number Lease Rate

Each leased number is subject to a base monthly lease rate (the "Base Rate"). The Base Rate covers only the right to lease and maintain the number. The Base Rate does not include:

(a) Any capability add-ons (SMS/MMS, Voice, iMessage, WhatsApp);

(b) Usage charges for capabilities billed based on usage;

(d) Any other services or features.

The Base Rate is the minimum monthly charge to hold a leased number, regardless of whether you actively use the number or any capabilities. Current Base Rate pricing is available at contiguity.com/pricing and may be updated at any time.

3.2 Paused Numbers

If you pause a number while keeping it active and leased (i.e., maintaining the lease without active use), you remain responsible for the full Base Rate. Pausing does not reduce or eliminate the monthly lease charge.

3.3 Capability Add-Ons

Each capability (SMS/MMS, Voice, iMessage, WhatsApp) is priced separately and billed in addition to the Base Rate. Current pricing for capability add-ons is available at contiguity.com/pricing and may be updated at any time.

Most capabilities are provided on an unlimited basis (unlimited messages or usage). Certain capabilities, such as Voice, may be billed based on actual usage (e.g., per-minute charges for calls).

3.4 Setup Fees

One-time setup fees may apply when:

(a) Initially leasing a number;

(b) Adding new capabilities to a leased number;

(d) Requiring expedited provisioning;

(e) Paying for hardware, infrastructure, or systems required to support a specific number (if applicable); or

(f) Other circumstances as determined by Contiguity.

Applicable setup fees will be communicated to you before you complete the lease or capability activation. Setup fees are non-refundable under all circumstances. Payment of setup fees does not entitle you to any ownership rights in hardware, infrastructure, licenses, systems, or any other assets used to provide the leased number or related services.

3.5 Use Case Surcharges

Depending on your use case, industry, messaging volume, or other factors, Contiguity may apply a use case surcharge to your monthly rate. Use case surcharges are determined by Contiguity in its sole discretion and may include:

(a) Higher-risk industry surcharges (e.g., cannabis, crypto services, debt collection);

(b) High-volume messaging surcharges; or

You will be notified of any applicable use case surcharges before your lease is finalized. Contiguity may adjust use case surcharges upon 30 days' notice if your use case changes or if Contiguity determines a surcharge adjustment is warranted.

3.6 Billing Without a Service Contract

If you are not enrolled in a Service Contract, number leasing charges are billed as follows:

(a) Base Rate: Billed monthly in advance on the first day of each billing cycle.

(b) Capability Add-Ons: Billed monthly in advance or according to the pricing structure for each capability (unlimited capabilities billed in advance; usage-based capabilities billed in arrears).

(c) Usage Charges: For capabilities billed based on usage (e.g., Voice), charges are billed in arrears based on actual usage.

(d) Setup Fees: Billed immediately upon number provisioning or capability activation.

All charges are non-refundable except as expressly stated in the Contiguity Services Agreement.

3.7 Billing Under Service Contracts

If you are enrolled in a Service Contract, number leasing charges are handled as follows:

(a) Included in Monthly Fee: The Base Rate, capability add-ons, and usage charges for leased numbers are included in and applied against your Service Contract's fixed monthly fee amount.

(b) Setup Fee Treatment: Setup fees for leased numbers may be waived or reduced as a Service Contract benefit, as specified in your Service Contract configuration.

(c) Use Case Surcharges: Use case surcharges, if applicable, are included in your Service Contract amount or may be billed separately as determined by Contiguity.

(d) Overage Calculation: Number-related charges count toward your total monthly usage when calculating potential overages under your Service Contract.

For more information on Service Contract billing, see the Service Contract Terms.

3.8 Rate Changes

Contiguity may adjust pricing for number leasing, capability add-ons, setup fees, and use case surcharges at any time upon 30 days' written notice, in accordance with Section 4.1 of the General Terms. Continued use of leased numbers after the effective date of a rate change constitutes acceptance of the new rates.

4. Number Management

4.1 Number Changes and Replacements

You may request to change or replace a leased number at any time, subject to availability and Contiguity approval. Number changes may be subject to setup fees and may require re-provisioning of capabilities. See Section 5 for information on covered replacements due to carrier filtering or blocking.

4.2 Area Code and Geographic Assignment

Leased numbers are assigned from available inventory. While you may request a specific area code or geographic region, Contiguity does not guarantee availability of any specific area code or location. Numbers may be reassigned to different geographic regions at any time due to carrier decisions or industry regulations.

5. Carrier Filtering, Blocking, and Number Replacements

5.1 Carrier Filtering and Blocking

Telecommunications carriers may filter, block, rate-limit, or otherwise restrict numbers based on:

(a) Content of messages or calls;

(b) Sender reputation or spam scores;

(d) Compliance with carrier policies;

(e) Suspected fraud or abuse; or

(f) Other factors determined by carriers.

Contiguity has no control over carrier filtering or blocking decisions. Carriers do not provide advance notice of filtering or blocking, and Contiguity cannot predict, prevent, or reverse carrier actions.

5.2 Number Bans and Suspensions

If a carrier bans, suspends, or permanently blocks a number, the number may become unusable for some or all capabilities. In such cases:

(a) Contiguity will make reasonable efforts to notify you of the issue;

(b) You remain responsible for the monthly lease fee unless you terminate the lease or Contiguity provides a replacement under Section 5.3;

(c) Contiguity is not responsible for revenue loss, business disruption, or other damages resulting from carrier actions; and

(d) Contiguity may, in its sole discretion, terminate the lease without penalty if the number becomes permanently unusable.

5.3 Covered Replacements

Covered Replacements are goodwill replacements of filtered or blocked numbers that Contiguity may provide at its sole discretion in certain circumstances. Covered Replacements are subject to the following:

(a) Eligibility: Covered Replacements are typically offered only when: (i) The number was filtered or blocked due to carrier error, not your conduct or content; (ii) You have maintained good standing and compliance with all Contiguity Terms; (iii) The filtering or blocking was not caused by violation of carrier policies, spam, fraud, or abusive content; (iv) You promptly reported the issue to Contiguity; and (v) Contiguity determines, in its sole discretion, that a Covered Replacement is appropriate.

(b) Not Guaranteed: Covered Replacements are a goodwill service and are not guaranteed. Contiguity has sole discretion to determine whether a replacement qualifies as a Covered Replacement.

(c) Limits: Covered Replacements may be limited to a certain number per account per year (typically 2-3 replacements) or per individual number. Excessive filtering or blocking issues may indicate compliance problems and may result in denial of further Covered Replacements.

(d) No Fees for Covered Replacements: When Contiguity approves a Covered Replacement, setup fees for the replacement number are typically waived. However, you remain responsible for all other applicable charges.

(e) Timing: Covered Replacements are provided on a best-effort basis. Contiguity does not guarantee any specific timeline for provisioning replacement numbers.

5.4 Non-Covered Replacements

If Contiguity determines that a number replacement does not qualify as a Covered Replacement (e.g., because the filtering resulted from your conduct, content, or policy violations), you may still request a replacement number, but:

(a) Standard setup fees will apply;

(b) The replacement is subject to Contiguity approval;

(d) Repeated non-covered replacement requests may result in denial of further number leases or termination of your account.

5.5 Your Responsibilities

You are responsible for:

(a) Following all carrier content guidelines and messaging best practices;

(b) Monitoring your number's deliverability and reputation;

(d) Providing accurate information about your use case; and

(e) Complying with all applicable laws and regulations.

Failure to meet these responsibilities may result in numbers being filtered or blocked, and such issues will typically not qualify for Covered Replacements.

5.6 No Delivery Guarantees

Contiguity does not guarantee any specific delivery rates, call completion rates, or quality of service for leased numbers. Delivery and performance depend on factors outside Contiguity's control, including carrier networks, recipient carrier policies, device settings, and network conditions.
