These Trademark Usage Guidelines are for Twilio Inc.'s licensees, authorized resellers, developers, customers, and other parties who wish to use Twilio's trademarks, names, and logos ("Twilio Trademarks") for their own purposes, including in promotional, advertising, instructional, or reference materials, or in or on web sites, products, labels, or packaging. Note that any use of Twilio logos and/or use of any Twilio Trademarks outside of these guidelines requires permission and without such permission may constitute trademark infringement under federal and state laws.

Twilio Trademarks

Twilio Trademarks are valuable assets Twilio needs to protect. We ask that you help us by properly using and crediting Twilio Trademarks in accordance with these guidelines. The Twilio Trademarks specifically include:

  • The Twilio Rotary logo

Permissible Uses

You may generally use the TWILIO and TWIML trademarks to refer to the associated Twilio products or services. For instance, an authorized developer may note in its advertisements and products that it utilizes the Twilio software. Similarly, such a developer may issue a press release stating that it has built its product on the Twilio platform.

Relationship of Products or Services

You may indicate the relationship of your products or services to Twilio products or services by using accurate, descriptive tag lines such as "with Twilio technology," "built on the Twilio platform" in connection with your product or service name. Within text or body copy, such tag lines may appear in the same type as your product or service name. On product, packaging, advertising and other collateral where your product or service name is displayed apart from body copy, make sure that the tag line appears in significantly smaller type than your name. You should also distinguish the tag line from your mark by using a different font or color.

Open Source Software

Most open source licenses do not grant, and many exclude, a license of trademark rights. Do not assume you can use the name of a source code base in the name of your distribution developed from that code base. Without a license or permission, you may not incorporate Twilio Trademarks in the name of your distribution or other products that incorporate open source elements. Truthful statements incorporating a trademark are generally allowed (for example, in the format "MyImplementation, derived from Trademarked ProductName"), but you should check the terms of the license for the original source code or any posted trademark guidelines for the project.

User Groups

Twilio generally permits use of its marks in groups name that include phrases such as "user group," "special interest group," etc., that clarify the relationship between Twilio and the group and do not create confusion about the source of products or services. This applies only to user groups that are not formally doing business as commercial entities. If you are administering a user group that includes a Twilio trademark in its name, do not claim any trademark rights in the name or attempt to register the name or your logo with a trademark office, and do not register the name as a trade name or business name, or conduct any business under the name.

Correct Use

Proper use of Twilio Trademarks reinforces their role as brands for our products and services, and helps prevent them from becoming generic names that can be used by anyone. Examples of former trademarks that became generic terms are "aspirin," "cellophane," and "escalator." By adhering to the following rules, you help protect Twilio's investment in its trademarks.

Use a Generic Term

Use a generic term in association with each Twilio trademark the first time the mark appears in text, and as often as possible after that. You need not include generic names in headlines, package titles and documentation titles. "Twilio platform" is an example of generic term use.

Use as Adjectives

Twilio Trademarks are adjectives and should not be used as nouns, or in the possessive or plural form. For example, "Twilio platform's benefits" not "Twilio's benefits"

Do Not Vary the Trademarks

Do not vary Twilio Trademarks by changing their spelling or abbreviating them. For example, "Twilio OpenVBX platform" not "TwilVBX" or the like.

Do not use any name or trademark confusingly similar to the Twilio Trademarks or any other trademark or trade name owned by Twilio for which Twilio has not given you permission. And do not use the Twilio Trademarks in such proximity to any of your own trademarks or trade names or third party trademarks so as to create a combination or composite mark.

"Twilio" As a Trade Name

Trade names are the actual business names of companies. Trademarks and trade names are not the same, even though many companies use their trade names as trademarks. If you are using "Twilio" as a substitute for Twilio Inc., you are using it as a trade name. Because they are nouns, trade names can be used in the possessive and do not require a generic term or a trademark symbol. Thus, you should not use a ® after "Twilio" when it appears as part of the full corporate name or as a trade name.


  • Corporate Name: This software was developed by Twilio Inc.
  • Trade Name: This software was developed by Twilio.
  • Trade Name: Twilio's latest software developments are outstanding.
  • Trademark: The Twilio® platform leads the industry.

Trademark Symbols And Credit Lines

Trademark Symbols

Proper trademark attribution through trademark symbols and credit lines helps make others aware of our rights, and helps prevent them from becoming generic terms. Credit lines also help clarify that they belong to Twilio. Accordingly, you should attribute ownership of Twilio Trademarks to Twilio Inc. by using trademark symbols (™ or SM or ®) and credit lines as detailed below.

Use the ® symbol with the most prominent appearance of the "Twilio" mark on products, packaging, manuals, advertisements, promotional materials and Web pages (for example, in the headline of an advertisement), and the first use of the mark in text or body copy. This includes situations where "Twilio" is a part of a product or service name (for example, Twilio® Twiml® platform). An example would be

XYZ Develops New Product on the Twilio® Platform XYZ Corporation has developed the ABC telecommunications app based on the Twilio® platform. The ABC app is one of numerous products XYZ has developed using Twilio software.

"Twilio" receives a trademark symbol in the headline because this is the most prominent appearance, and when it appears as part of the "Twilio platform" name because this is the first appearance in text. While there is no trademark symbol after "Twilio" when it appears in front of the term "software" since this is not the first time that the term "Twilio" appeared in body copy. That said, it is always acceptable to continue using the ® after "Twilio" throughout the document.

Credit Line

All products, packaging, manuals, advertisements, promotional materials and web pages bearing Twilio Trademarks should include the following trademark credit line.

"Twilio and Twiml are registered trademarks of Twilio and/or its affiliates. Other names may be trademarks of their respective owners."

The credit line may appear anywhere on the collateral, but typically is displayed on a copyright page, the back of a package or at the end of a document or web page.

Prohibited Uses

You may not use the Twilio Rotary Design logo or the MODERN COMMUNICATIONS tagline without express written permission from Twilio.

You may not use any of the Twilio Trademarks

  • in a manner that could cause confusion as to Twilio sponsorship, affiliation or endorsement; or
  • in a manner that shows Twilio or its products in a false or derogatory light

Take particular care not to use Twilio Trademarks as set out below.

Company, Product or Service Names

Do not use Twilio Trademarks or potentially confusing variations as all or part of your company, product or service names. If you wish to note the relationship of your products or services to Twilio products or services, please use an appropriate tag line as detailed above. For example, "XYZ for Twilio database" not "TwiXYZ or XYZ Twilio"


For more information regarding use of Twilio logos, please review the Third-Party Twilio Logo Usage Guidelines.

Trade Dress

You may not imitate Twilio trade dress, type style or logos. For instance, do not copy Twilio's layout or styling of its web pages for use with your product, or display your product name in the distinctive logotype associated with the Twilio logo.

Domain Names

Do not use Twilio Trademarks or potentially confusing variations in your Internet domain name. This helps prevent Internet users from being confused as to whether you or Twilio is the source of the web site.

Merchandise Items

You may not manufacture, sell or give-away merchandise items, such as T-shirts and mugs, bearing any of the Twilio Trademarks or any other Twilio marks or names, including symbols, logos, or icons, except pursuant to an express written trademark license from Twilio.

Report Usage Violations

Please report suspected misuse of logos, trademarks or copyrighted material to
