UPC Code Formatting Requirement – Effective January 1, 2026

Beginning January 1, 2026, violations will be issued for incorrectly formatted UPC Codes in Flexmls.

What you need to know:

• The UPC Code field must be entered as numbers only — no dashes or spaces.
• Entering dashes or spaces will trigger a Listing Data Checker violation.
• Only one UPC Code may be entered in the designated UPC Code field.
• Any additional UPC Codes or short legal descriptions must be included in the LO/SO Remarks field.

Important deadlines:

• Brokers have until end of day December 31, 2025 to review and correct existing listings.
• The Listing Data Checker rule goes live at 12:01 a.m. on January 1, 2026.

After the rule is active:

• Listings with incorrectly formatted UPC Codes will receive a violation notice.
• If the issue is not corrected within 48 hours, a fine will be issued in accordance with SWMLS policy.

Existing listings:

If you find older listings with UPC Codes that include dashes or spaces, contact SWMLS staff immediately. These records must be corrected manually.

Why this matters:

• Correct UPC entry ensures accurate property history, preserves MLS data integrity, and allows proper linking to county records.
• Any intentional attempt to prevent a listing from linking to its property history may be considered MLS data manipulation and could result in additional violations and fines.
