Serial number decoder for Bradford White

Serial no.

Type the serial from the data plate, not the model number. Nothing is sent anywhere; the tables are in this page.

Format example: DG6322957

Bradford White boiler serial numbers in the 1984 to present format encode the year as letter 1, 20-year cycle (table below) and the month as letter 2 (table below) (source: bradfordwhite.com).
Example: serial DG6322957 decodes to 1987 or 2007 (July).
The 1984 to present format is ambiguous: Year letter repeats every 20 years (A = 1984, 2004 AND 2024; as of 2026, A/B/C are triple-ambiguous). Disambiguate via ANSI compliance date on the plate, rating-plate style, or the official my-water-heater lookup which returns the exact manufacture date. Special case: 'OA' serials exist due to a computer error, all made January 1997.
Bradford White's official lookup at bradfordwhite.com returns manufacture date (official date decoder + printed letter chart).
