The San Gabriel/Pomona Regional Center relies on our vendored service providers to meet the needs of our community. The Community Services Department is the division that identifies recruits, and maintains qualified services providers. Our expectation is that our vendored service providers share SG/PRC’s vision and commitment to providing quality services to our diverse population and their families. When becoming a vendor, you will primarily work with our resource development staff and vendor coordinators.
Resource Development
Our Resource Developers provide outreach to prospective individuals and entities interested in providing services to our community. Resource Developer’s provide technical assistance throughout the vendorization process and help to ensure the services both meet the current needs and are in compliance with applicable laws, regulations, SG/PRC Board policies, and/or ordinances.
The Resource Developers are available to assist with finding generic resources or identifying and vendoring a resource that are needed to meet the needs of individuals served .

How to Become a Service Provider/Vendor?
Service providers must be vendored by a regional center before they can provide and be reimbursed for services agreed to by each IPP Team. The following describes how to become a vendored service provider.
What is Vendorization?
“Vendorization” is the term used to describe the approval process to provide services through regional centers to individuals with intellectual and developmental disabilities. You apply for vendorization online through the Provider Directory. This is where you will submit required information and documents, communicate with regional centers, and track your progress.
Your application will be reviewed by the vendoring regional center – the center responsible for the geographic area (also known as catchment area) where your site-based service or operating office is located. The regional center will review your documents and determine if you meet the requirements. If approved, you’ll be assigned a vendor number and a service code in the Provider Directory.
When should you apply for vendorization in the Directory?
Applicants can start a vendorization application at any time. However, if applying for an emergency vendorization or applying for vendorization of certain specialized facilities through the Community Placement Plan (CPP) or Community Resource Development Plan (CRDP) project, contact SG/PRC at vendorization@sgprc.org to learn how to begin your application process and when to create your login profile to apply in the Provider Directory. Vendorization does not guarantee that individuals will be referred to or placed with a vendored provider [Title 17 of the CCR section 54322(d)(10)].
Vendorization Process:
The vendorization process is done online through the Provider Directory. Here’s what to expect:
Step 1: Create or login to existing Provider Directory Profile

- If not approved, you’ll receive a denial notice with the right to appeal the decision.
All document submissions between the applicant and the regional center must take place in the Provider Directory. The Provider Directory can also be used for ongoing communication. The Provider Directory system supports deadline tracking through automated notifications.
Who Can Use Vendored Providers?
Once vendored, a service provider may be utilized by individuals served by other regional centers, known as “user,” “utilizing,” “courtesy,” or “shared” regional centers, as well as the originally vendoring regional center.
NOTE: The vendor identification number assigned by the vendoring regional center must be used by all regional centers purchasing the vendored service in the situation above.
