Answers to FAQs about Verified Products Portal

We answered frequently asked questions about the Verified Products Portal, implementation with the Multiple Award Schedule Solicitation refresh dated May 17, 2021. Updated information is provided specific to the updated Letter of Supply requirements under Refresh 27, dated June 26, 2025.

What is the Verified Products Portal?

The Verified Products Portal, or VPP, is a manufacturer-facing portal where participants can provide authoritative product content and supplier authorization information. This content is provided by manufacturers or their authorized partners and will include data elements such as, but not limited to:

• Supplier authorization details
  • Authorized resellers (“vendors”)
  • Product lines
  • Doing business as
• Product category details
  • Product brand name
  • Manufacturer part number
• Product details
  • Descriptions, including if the product is remanufactured
  • High and low resolution product images
  • Features
• Supply chain attributes
  • Country of origin
• Pricing information (optional)
  • Threshold for which the authenticity of the product is questionable
  • Date of upcoming price increases from the manufacturer

How will GSA use VPP data to manage MAS catalogs?

The GSA acquisition workforce is required to review VPP data, as presented via the Compliance and Pricing Report, to determine vendor authorization status when reviewing new offers, modifications, and contract options. The workforce will be notified whether a vendor is authorized, unauthorized, or requires a Letter of Supply (LoS) because the product does not exist in VPP. Below are the terms and definitions provided:

Definition of terms:

• “Authorized” indicates the manufacturer is providing supplier authorization details to the VPP and the vendor is an authorized reseller. This vendor does not need a LoS.
• “Unauthorized” indicates the manufacturer is providing supplier authorization details to the VPP and the vendor is not an authorized reseller. The product must be removed from the offer, modification, or contract.
• “Review LoS Requirements” indicates the manufacturer of the product is not providing supplier authorization details to the VPP and:
  •  A Letter of Supply is required to be submitted if the item(s) is under a SIN within the Information Technology Large Category (Category F) or a SIN within the Printing and Photographic Equipment Subcategory (A10) under the Office Management Large Category (Category A).
  • A Letter of Supply is not required for items under any other Large Category or Subcategory, except as stated above. 
    • Note: In accordance with clause I-FSS-644 PRODUCTS OFFERED AND SOLD BY VENDORS OTHER THAN THE MANUFACTURER (DEC 2022), Contractors shall not offer or sell products under this contract for which they do not have authorization, as applicable, and they lack an uninterrupted source of supply sufficient to satisfy the Government’s requirements. If at any point an offeror/contractor becomes unauthorized, or cannot provide a continuous source of supply, it’s the contractor’s responsibility to remove the item(s) from the contract. 

How does VPP implementation impact Letter of Supply (LoS) requirements?

If you offer commercial off-the-shelf (COTS) products under a Large Category, Subcategory, or SIN that requires a Letter of Supply  and your proposed products come from a manufacturer who provides supplier authorization data in the VPP, then you no longer need to submit an LoS for those products.

If the manufacturer is not registered in VPP or does not provide supplier authorization data in VPP, as of MAS Refresh 27, Letters of Supply are only required for products offered under the Information Technology Large Category (Category F) and the Printing and Photographic Equipment Subcategory (A10) under the Office Management Large Category. Under all other Large Categories/Subcategories, vendors are responsible for ensuring they are authorized and will provide a continuous source of supply pursuant to I-FSS-644 requirements. 

Why is GSA implementing the VPP?

The VPP is a part of the Federal Marketplace Strategy, GSA’s plans to modernize and simplify the buying and selling experience for customers, suppliers, and acquisition professionals. Implementation of the VPP will protect against supply chain risks and decrease a buyer’s risk of purchasing counterfeit or otherwise non-compliant products. Purchasing counterfeit items poses a large risk to our customers, and can have negative impacts such as a voided manufacturer warranty. VPP implementation means buyers can purchase with increased confidence that the product is legitimate. Implementation will also decrease the burden on industry associated with managing Letters of Supply.

Does this apply to all modifications?

Yes, the GSA acquisition workforce will review VPP data each time they evaluate product modifications.

How do I know if the manufacturers who produce my products participate in the VPP?

We maintain a dashboard of VPP participants that is updated daily. Please visit the Verified Products Portal Participation Dashboard for more information.  Additionally, supplier authorization information is provided at the individual line item level, via the FAS Catalog Platform (FCP), which automatically generates a Compliance and Pricing Report.  If the contract is not yet FCP eligible, your Contracting Officer may choose to analyze your proposed products through our new Compliance and Pricing Reporting Portal.

What do I do if the manufacturers producing my products are listed on the VPP dashboard?

You should not collect and provide a LoS. You should follow all other parts of the traditional offer or modification process.

What do I do if the manufacturers who produce my products are not VPP participants?

You should ensure you can meet the requirements of I-FSS-644 prior to offering a product. For items awarded, it is the vendor’s responsibility to ensure they are authorized and will be able to provide a continuous source of supply as required pursuant to I-FSS-644.

A Letter of Supply [DOCX - 17 KB] is required for items under an Information Technology Large Category SIN or Printing and Printing Supplies Subcategory SIN within the Office Management Large Category. A LoS template is available for download on the MAS Available Offerings Site

What happens if GSA determines I am unauthorized based on VPP data?

GSA will not approve products you are not authorized to sell. You should remove the product(s) from your offer or modification. Failure to do so may result in the offer or modification being rejected.

If you believe that the VPP does not have the correct information you may do one of the following:

• If you believe you are authorized, you should work with your manufacturing partner to get the VPP data updated. Once the VPP data has been updated, resubmit the offer or modification.
• If you believe there is a data error, contact VPP@gsa.gov.

Does GSA intend to make VPP mandatory? 

No, VPP participation is optional for manufacturers.

Will existing contract holders be required to submit updated LoS?

If no authorization status is listed in VPP, a LoS is only required for SINs under the Information Technology Large Category (Category F) and Printing and Photographic Equipment Subcategory (A10) of the Office Management Large Category (Category A). For the SINs that require a LoS, as long as your existing LoS is current and accurate, there is no need to submit a new one in response to the solicitation refresh.

How often do I need an updated LoS?

You are responsible for maintaining a current LoS with your supplier(s) for the duration of the MAS contract period and any extensions thereof; any changes to the relationship with your supplier(s) will require a new LoS. In addition, the LoS will be reviewed at time of contract option.

What if my products come from a wholesaler?

The VPP is currently capturing supplier authorization information from manufacturers who directly manage authorization programs. If the manufacturer of your products is participating in VPP, you will need to be listed by that manufacturer, regardless of whether or not your products come from a wholesaler.

If the manufacturer does not directly manage their authorization program and instead delegates that authority, they are likely not participating in VPP at this time. However, an upcoming enhancement to the VPP will let manufacturers delegate rights to authorized partners to manage authorization lists to authorized partners. At that time, manufacturers can identify their authorized partners and those partners can provide supplier authorization information to the VPP. In the event GSA has only partial authorization coverage for a single manufacturer, GSA will default to traditional requirements in the absence of VPP data.

What happens if the manufacturer does not want to approve a vendor requesting a LoS to sell their products and the manufacturer is on VPP?

If a manufacturer is participating in VPP, VPP data is authoritative for products offered by that manufacturer. If a manufacturer does not approve a vendor to sell their products, then that vendor is not authorized to sell those products, and they should be removed from the offer or modification.

What if a manufacturer authorizes different products to different vendors?

VPP participants can set authorization rights at the product level to address this scenario.

Who do I contact for an issue with VPP data?

Issues with VPP data should primarily be resolved with your manufacturing partner. If your manufacturing partner is having a technical issue or believes the data displayed is inaccurate, contact VPP@gsa.gov.

How will GSA ensure VPP participant authenticity?

Currently, VPP participants are manually verified by the GSA Catalog Management Office.

What if I am the manufacturer?

This Q&A is for products offered and sold by vendors other than the manufacturer and does not apply to manufacturers. However, we strongly encourage manufacturers to participate in VPP.

Will manufacturers be able to make continuous updates to specs in the VPP?

Yes, manufacturers can update their products manually or automatically through an Application Programming Interface (API) connection, enabling easy, frequent updates.

Will the VPP apply to services offered?

No, VPP only collects data for commercial off-the-shelf (COTS) products.

How will GSA use the pricing information in the VPP?

VPP data will become another data source for the Price Point API already in use by the acquisition workforce.

Will customers have access to the VPP?

No, only manufacturers and their authorized partners, as well as select GSA staff, have access to the VPP.

How will the VPP impact GSA Advantage?

GSA will utilize VPP data to augment vendor catalogs with manufacturer-provided content similar to the way GSA currently uses master data sources to offer an “Additional Description” field to customers on Advantage.

Will the VPP replace the Schedule Input Program?

No, the VPP is a manufacturer-facing portal for product details and supplier authorization content. The VPP is not intended for MAS contractors to use for managing their catalog data.

GSA is developing the FAS Catalog Platform (FCP) to offer a modern replacement to SIP that integrates with contracting processes. You can go to the Catalog Management Interact page to learn more.

How do I get a VPP account? 

VPP accounts are only for manufacturers and their authorized wholesalers/distributors. If you fit this description, contact VPP@gsa.gov about an account. 

What are the benefits to the manufacturer? 

Listing in the VPP:

• Ensures products are accurately represented to customers -manufacturers control the product details and marketing content.
• Eliminates variability among identical products through standardized catalog data provided directly by the manufacturer or a trusted source.
• Improves your customer’s experience by providing rich syndicated product content such as videos and product manuals.
• Allows manufacturers to authorize and deauthorize products and resellers in near-real time to protect against supply chain risks and ensure product and vendor authenticity.
• Reduces the burden on your vendors to provide letters of supply and product specifications -manufacturers control who can sell products and what product lines they can sell.
