Successfully validating your UEI number on SAM.gov requires accurate business information that matches existing records. Entities must provide a physical address (not P.O. Boxes), proper documentation including Articles of Incorporation, EIN confirmation letters, and business licenses. Common validation issues include address errors and name discrepancies between documents. Prompt responses to validation requests expedite the process, while supporting documents must be submitted through SAM.gov’s secure portal. The following guidance offers specific steps to navigate validation challenges effectively.

ToggleUnderstanding the SAM.gov Entity Validation Process

The entity validation process serves as the foundation for obtaining a Unique Entity ID (UEI) through SAM.gov. This verification system guarantees all business information submitted matches existing records before granting entity registration approval.
When an organization begins the validation process, the Entity Validation Service (EVS) automatically verifies submitted details against established databases. P.O. Boxes are not accepted as physical addresses during the initial registration steps. The validation timeline varies considerably depending on the accuracy of provided information and whether documentation is required to resolve discrepancies.
Entity validation timelines fluctuate based on data accuracy and whether supporting documentation becomes necessary for resolving discrepancies.
If the system identifies inconsistencies, an incident is created that requires resolution. Organizations must submit supporting documents through SAM.gov’s secure portal to address these issues. Users will receive email notifications upon completion of the validation process with instructions for next steps.
Prompt responses to validation requests are essential, as delays in submitting correct documentation directly impact the overall timeline for obtaining a valid UEI number. Regular compliance reviews of your entity’s registration details are recommended to maintain eligibility for government contracts and grants.
Required Documentation for Successful UEI Validation

Successful validation of your Unique Entity ID (UEI) requires meticulous preparation of essential documentation that accurately represents your organization’s legal identity.
The document preparation process focuses on gathering materials that confirm your entity’s legitimacy for proper entity verification.
Key required documents typically include:
- Articles of Incorporation showing your legal establishment date
- Business licenses relevant to your jurisdiction
- EIN confirmation letter from tax authorities
- Certificate of Good Standing from your state
- DBA certificates, if operating under an alternate name
All submitted documentation must maintain consistent information across every form, particularly regarding your legal business name, physical address, and incorporation date.
Inconsistencies between documents and your SAM.gov registration information commonly cause validation delays or rejection.
While an EIN is typically required, there are specific exceptions available for individuals or entities that don’t have one when registering in SAM.gov.
Troubleshooting Common UEI Validation Issues

Many organizations encounter significant obstacles during the UEI validation process, leading to delays in federal government participation opportunities. Address errors represent one of the most frequent challenges, particularly for rural entities.
The system requires USPS-formatted street addresses and does not accept P.O. Boxes as physical locations, causing validation failures when documentation doesn’t match these requirements.
Name discrepancies, even minor ones, can also trigger validation issues. GSA is implementing automation tools to resolve these problems more efficiently, including a robomod solution for small discrepancies.
Even small name inconsistencies can derail UEI validation, prompting GSA to develop automated fixes for minor discrepancies.
More substantial name changes must follow the standard modification process, with entities receiving notifications about any automated corrections. Entity Administrator roles are now strictly limited to employees, officers, and board members of the organization. Maintaining accurate registration information in the system is crucial for preventing compliance issues that could affect your eligibility for government contracts. Entity Administrators can view the current status of registration in the Workspace menu on SAM.gov to track validation progress.
For organizations facing manual reviews, which affect approximately 20% of applicants, patience is necessary as GSA prioritizes critical cases to reduce validation timeframes.
Frequently Asked Questions
How Long Does the UEI Validation Process Typically Take?
The UEI validation timeline typically ranges from 7-12 business days for standard processing, with activation taking up to 10 additional days. Processing delays may occur due to documentation discrepancies requiring manual review.
Can International Entities Obtain a UEI Number?
Yes, international entities can obtain UEI numbers. Foreign registration follows the same process as domestic organizations through SAM.gov. International eligibility is guaranteed, as UEIs are required for all entities conducting business with the Federal Government.
Is UEI Validation Required for Subcontractors?
Subcontractors are required to obtain a UEI number but don’t need complete SAM registration. Subcontractor requirements include having a valid UEI registration for federal contract reporting, particularly when prime contractors report subcontracting dollars.
What Happens if My Entity Operates From Multiple Addresses?
Entities operating from multiple locations must register each physical address separately in SAM.gov. Each location requires its own UEI and must undergo independent address verification through the Entity Validation Service to maintain compliance.
Can I Use My UEI for State-Level Government Contracts?
State contracts may or may not require UEIs, as requirements vary by jurisdiction. Entities should check specific state procurement processes, as UEIs are primarily mandated for federal contracts rather than state-level government transactions.
