As one of the largest telecommunications companies in the world, AT&T outsources a lot of its telecommunications work to outside vendors and contractors. It also needs suppliers in other areas that keep the company functional. To become a vendor for AT&T, you need to prove your company meets several criteria before it accepts you. Besides the company needing proof of financial stability, it wants to ensure that you have experience and have existing customers that value your services. Be prepared to show that your firm has the ability to supply the products and services to AT&T at competitive prices. It also helps to have established relationships within the industry.

Verify that you meet the minimum qualifications to be a vendor for AT&T. The company requires all of its vendors to maintain active insurance policies addressed to the level of risk their business faces. You will need to add AT&T as an additional insured and provide certificates of insurance to the company. At minimum, AT&T requires general liability insurance, automobile and workers' comp insurance, unless you are an independent contractor without employees. If you do any kind of legal work for AT&T, such as lease negotiation or review, be prepared to show proof of a professional liability or errors and omissions policy.

Maintain excellent relationships with your existing customers. AT&T will contact them for a reference as to your status as a vendor. Be able to provide company financial statements that support financial stability for your firm. The longer you have been in business, the better. It also helps to have worked with people in AT&T or other telecommunications companies unless you plan to provide office supply, janitorial services, graphic design, printing or similar services to AT&T.

Click the "Register Now" button on the AT&T supplier website. Enter your company name and email contact information. When you have submitted this information, AT&T will send you an email with a password for you to confirm. Use the email address you provided and the password sent to you by the company to log onto the site.

Fill in page one with your company name, state of incorporation -- if any -- and a primary Standard Industrial Classification code. This is a federal code that indicates what service or product you provide. For example, if you supplied blank checks to AT&T, your code would be 6770. Choose the code closest to your business in the resource guide.

Continue filling in the information, such as your address, a description of your products and services, and whether you represent more than one company as a distributor. After you have completely filled in the information on this page, press "Save" and go to the commodity area, where you will check boxes that show what you provide. Click the "Next" button. This will take you to the subheaders of the commodities you have selected. Put checks in the appropriate boxes

Complete the "Additional Information" page. You will answer questions concerning your company and industry. AT&T also wants to know if you already have a contract with the company, plus basic information about your company or executive staff's certifications. This page also asks for your sales projections and the year used for the figure listed.

Fill in the questionnaire, if any, as not all types of businesses require them. When you have completed it, you will be taken to a summary page where you can view all the information you have provided. If there are any errors, you may go back and correct them; otherwise, you may submit the information and log out. If AT&T has any further questions concerning your application, the company will send you an email.


  • Be prepared to offer competitive pricing. If AT&T is interested in doing business with your firm, it will send you a request for proposal, which will include an area that requires you to provide pricing information to the company.

    Follow the instructions for responding to the request for proposal in the format requested and by the deadlines the company lists.
