AT&T spends tens of billions of dollars a year on outside goods and services, from fiber and network gear to facilities, marketing, logistics, and professional services. Getting a slice of that is less about filling out the right form and more about being known to a sourcing manager when a need comes up. The form takes 20 minutes. The relationship takes years.
This guide walks the actual path: how registration works, what AT&T's supplier inclusivity effort is and what it accepts, the Tier 2 route most owners overlook, and a recent policy shift you should understand before you build your strategy around any diversity angle.
Start with registration. It's free and it doesn't commit AT&T to anything.Every prospective AT&T supplier starts the same way: you put your company profile into AT&T's prospective supplier database. That listing is what AT&T sourcing managers search when they're scoping a buy. You'll only hear back if someone needs more information about your product or service. Registering does not imply a contract or any intent to purchase. It puts you in the system, nothing more.
As of this writing, AT&T was revamping its supplier portal (attsuppliers.com), and the interim path was to complete a PDF profile form and email it to the supplier inclusivity team. Confirm the current method on AT&T's official supplier pages before you send anything, because the portal and the intake address have been in flux.
The profile asks for the basics a buyer needs to size you up:
- Legal business name and headquarters address
- Year established and years in business
- Annual revenue and employee count
- Website
- Small business status under SBA guidelines
- Any socio-economic or diversity certifications you hold
- A primary contact (name, title, phone, email)
- The products and services you sell
- Your primary NAICS codes
AT&T expects suppliers to clear a baseline before serious conversations start. Plan on being in business at least a year, carrying a federal taxpayer ID, holding the insurance coverage typical for your category, and being able to point to positive references from other customers. Specific requirements vary by what you sell. A construction subcontractor and a SaaS vendor get held to different bars.
The inclusivity program: what it is, what it acceptsAT&T runs one of the older corporate supplier diversity efforts in the country. Its Prime Supplier Program traces back to 1989. The company now uses the name Supplier Inclusivity, and its stated aim has been to connect certified minority-, woman-, veteran-, LGBTQ+-, and disability-owned businesses with chances to sell to AT&T.
If you want to be counted as a diverse supplier, AT&T requires valid third-party certification from an approved organization. A self-declaration doesn't qualify. In practice that means a certification from one of the national bodies:
- NMSDC for minority-owned (MBE)
- WBENC for women-owned (WBE)
- NGLCC for LGBTQ-owned (LGBTBE)
- Disability:IN for disability-owned (DOBE)
- NaVOBA or NVBDC for veteran-owned (VBE / SDVBE)
You upload your certificate as part of your profile, and you keep it current. An expired certificate drops you out of the diverse-supplier count, which is exactly the data AT&T reports to regulators and tracks internally. For AT&T's 2024 reporting year, the company reported more than $16 billion in diverse spend in its California Public Utilities Commission GO 156 filing, with women-owned business spend up over $375 million year over year. That number is the reason a sourcing manager has any incentive to find you.
If you're deciding which certification is worth the time and money, our corporate programs directory shows which companies accept which certifications, so you can target the ones that actually open doors at the buyers you care about. And if you'd rather hand off the filing across multiple agencies and bodies, CertifyAll handles the paperwork once instead of you running each portal separately.
A policy shift you need to factor in (late 2025)Here's the part most older guides won't tell you. In a December 2025 letter to FCC Chairman Brendan Carr, tied to regulatory approval of its roughly $1 billion spectrum and UScellular-related dealings, AT&T committed to ending its diversity, equity, and inclusion programs. The company stated it would no longer use DEI considerations in selecting suppliers and would not apply supplier requirements tied to race, gender, or sexual orientation. T-Mobile and Verizon made comparable commitments earlier in 2025 under similar FCC pressure.
What does that mean for you, practically? Two things. First, the public-facing "supplier inclusivity" language and the certification-acceptance mechanics may be changing or already changed by the time you read this. Verify the current state on AT&T's own pages rather than trusting any single article, including this one. Second, and more useful: a certification was never the thing that won you an AT&T contract. Capability, price, reliability, and being top of mind when a need surfaces are what win contracts. A diversity certification was a tiebreaker and a way to get found in the database. If AT&T pulls back on the diversity angle, the suppliers who were already competitive on the fundamentals lose the least.
So don't build your AT&T strategy on the certification alone. Build it on being a credible vendor who happens to be certified. That holds up no matter where the policy lands.
The route most owners overlook: Tier 2If AT&T's direct buys feel out of reach, and for most small companies they are at first, the faster door is often a side door. AT&T's Prime Supplier Program asks its large prime suppliers to use diverse and small businesses as subcontractors. That's Tier 2 spend: you sell to a company that sells to AT&T, and AT&T still counts and tracks your participation through the prime.
AT&T has run a virtual matchmaking tool to connect its primes with subcontractors that fit their needs. The math here is friendlier. A prime running a $40 million AT&T contract may need exactly the niche service you provide, and a prime is a far easier first sale than the mothership. Land a couple of prime relationships and you build the past performance and references that make a direct AT&T conversation realistic later.
Identify who AT&T's primes are in your category, and approach them the way you'd approach AT&T: with a tight capability statement and a specific problem you solve.
A realistic timelineSet expectations honestly. Registering takes an afternoon. Getting a real opportunity is usually measured in quarters and years, not weeks. Most suppliers who register never get contacted, not because the system is broken but because there wasn't a matching need when a buyer searched. The owners who break through tend to:
- Keep the profile current and specific, with the right NAICS codes and clear products
- Pursue Tier 2 prime relationships in parallel, not after
- Show up at the matchmaking events and supplier conferences where AT&T sourcing staff actually meet vendors
- Have a real differentiator, not just a certification
Treat registration as the start of a sales process, not the end of an application. The companies that win AT&T work are the ones who were already going to be good vendors and made themselves easy to find.
Where to go nextRegister, get certified if it fits your business, and then do the harder work of becoming the obvious choice in your category. Start by mapping which corporate programs accept your certification and where the real demand is, in our corporate programs directory. If you want a public profile buyers and primes can find, build one in our supplier directory.
