Serial number decoder for Bertazzoni range

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: 4220

Bertazzoni range serial numbers in the era not stated format encode the year as the rating tag carries a separate 'Prod. date' / 'Date prod.' field next to the 6-digit serial; its last two digits are the year (20 = 2020) and the first two digits of the Prod. date field = ISO week (42 = mid-October) (source: us.bertazzoni.com).
Example: serial 4220 decodes to week 42 of 2020.
Bertazzoni's official lookup at us.bertazzoni.com returns warranty / registration lookup.

Shape #### · example 4220 · confidence medium

Year: the rating tag carries a separate 'Prod. date' / 'Date prod.' field next to the 6-digit serial; its last two digits are the year (20 = 2020)
Week or month: first two digits of the Prod. date field = ISO week (42 = mid-October)

Example: serial 4220 decodes to week 42 of 2020.

Trap: Official Bertazzoni US 'How do I locate my model, serial number and production date?' PDF shows tags with Serial number 080367 + Prod. date 4220 (range) and Serial 082704 + Prod. date 4320 (built-in oven). The 6-digit SERIAL itself is a plain sequence with no date. The WWYY reading of the 4-digit field is an inference from the examples (42 and 43 cannot be years; both units are 2020 tags) - the PDF does not spell out the format, hence medium. Pattern applies to the Prod. date field, not the serial.

Where the data plate is on a range

Open the oven door or the storage drawer and look on the frame; slide-in ranges often carry it under the cooktop lip.

General guidance, not brand-specific: the owner's manual or the installer can point to the exact spot. See the data plate guide.

For scale only: the InterNACHI Standard Estimated Life Expectancy Chart for Homes lists Electric Range / Gas Range at 13 to 15 / 15 to 17 years of expected service (nachi.org). That chart is a guideline, not a prediction for your unit.

What we could not confirm

Official locator PDF: the tag has a separate Prod. date field (e.g. 4220) beside a 6-digit serial; WWYY reading inferred. Warranty statement curl 200 (terms only).
