When uploading documents to SAM.gov, users must first prepare essential files across five categories: entity documentation, authorization documents, financial information, classification codes, and verification materials. After logging in, navigate to the Entities Workspace, select appropriate document types from dropdown menus, and upload files in supported formats like PDF or JPEG. Make certain all documents are high-quality, consistent with registration information, and properly tagged to avoid validation delays. Following these submission protocols guarantees smoother processing of registration materials.

ToggleDocument Preparation: What You Need Before Upload

Five essential document categories must be prepared before attempting to upload attachments in the SAM registration system. Entities should create a document checklist that includes entity documentation, authorization documents, financial information, classification codes, and verification materials.
For U.S. businesses, this means gathering the Taxpayer Identification Number (TIN), EIN, legal name documentation, and physical address verification.
The upload process requires a notarized letter naming the authorized representative and stating the entity’s legal name and UEI (if available).
Financial attachments should include banking details for federal payments.
Classification documents should contain relevant NAICS and SIC codes, plus CAGE codes for U.S. entities or NCAGE codes for international registrants.
All documents must undergo verification for consistency with IRS and DLA records.
Periodic profile audits help ensure all uploaded documentation remains current and compliant with SAM requirements.
Step-by-Step Guide to Attachment Submission in SAM.gov

Now that all necessary documents have been prepared, the actual process of uploading attachments in SAM.gov follows a specific procedure.
Users must first navigate to the Entities Workspace after logging into their SAM.gov account. From there, they select the appropriate document type from the predefined options that accurately reflect the purpose of each file. Having multiple POC designations helps ensure proper document organization and streamlined communication during the registration process.
Navigation to the Entities Workspace is the gateway to successful document management within the SAM.gov ecosystem.
The system supports several document formats, including PDF and JPEG, which users can upload using the drag-and-drop interface. Document options may include articles of incorporation, bank statements, utility bills, or driver’s licenses for sole proprietors.
Following best practices, users should guarantee each file remains under the system’s size limits and is properly tagged.
After uploading, users must check verification boxes confirming the documents contain required information such as legal business name and address before submitting for validation.
Troubleshooting Common Document Validation Issues

Identifying validation issues early saves entities significant time during the SAM registration process. The validation process often stalls due to inconsistent data between documents and registration forms, particularly with address details or entity names.
Common errors include submitting poor-quality documents with blurry text, low contrast, or missing signatures. Entities should guarantee all attachments clearly display required seals, stamps, and signatures. Legal compliance officers can provide essential guidance for complex certification requirements.
When documents have mismatched information, providing clear explanations in the ticket text box becomes essential. Submit only required documentation as outlined by the Entity Validation System to streamline the review process.
To prevent validation delays:
- Check consistency across all submitted materials
- Use high-quality scanning equipment
- Verify all required fields are completed
- Communicate clearly with support agents about specific needs
- Respond promptly to requests for additional information
Frequently Asked Questions
Can Third-Party Representatives Upload Documents on My Entity’s Behalf?
Yes, third-party representatives can upload documents on an entity’s behalf during SAM registration.
With proper authorization, these agents can access the system to facilitate document management while maintaining document security protocols. The entity must provide formal written authorization specifying the third party’s details and responsibilities.
However, the entity remains ultimately responsible for all information submitted. Third party access is limited to data entry functions, and they cannot serve as entity administrators despite their document uploading capabilities.
How Long Does SAM.Gov Retain Uploaded Documents After Registration Expiration?
SAM.gov’s document retention policy after registration expiration is not explicitly stated in official guidance.
Documents remain viewable while a registration is active, but access becomes limited once expired. For risk management, entities should download and independently store all submitted documents before expiration.
The registration timeline of 12 months dictates when documents need review. Maintaining local backups guarantees continuity if reactivation becomes necessary, as expired registrations require complete document resubmission during renewal.
Are Document Requirements Different for International Versus Domestic Entities?
Yes, document requirements differ considerably for international versus domestic entities.
International guidelines require entities to obtain DUNS numbers or Unique Entity IDs and NCAGE codes, while domestic compliance focuses on U.S. taxpayer ID numbers (EIN/TIN) and bank account information.
International entities must provide locally registered business documents translated into English.
Domestic entities need to include incorporation dates and fiscal year end details.
Both must provide legal business names and physical addresses for proper verification.
Can I Pre-Validate My Documents Before Formal Submission?
SAM.gov does not offer a formal pre-validation service for documents before submission.
Entities can informally pre-check their documentation against submission guidelines by ensuring:
- Documents clearly show legal business name and address
- Files are in PDF format under 5MB
- Tax documents from the IRS or incorporation certificates are included
- Non-English documents have notarized translations
This self-review approach helps minimize validation delays during the official 3-5 day document validation process.
What Happens if My Bank Changes During Active Registration Period?
If a bank changes during an active registration period, the entity must update their banking information in SAM.gov immediately.
Bank changes require prompt action to prevent payment disruptions and maintain compliance. The entity should log into SAM.gov, navigate to their workspace, and update the banking details in the entity information section.
Failure to update this information can result in delayed payments, financial disruptions, and potential non-compliance with contractual obligations.
