How To Read Toothbrush Head Model Numbers

Keep the full code and slash suffix. Similar HX pack numbers are not automatically identical.

What matters for this question

The letters often identify a product line while digits and the suffix identify a particular pack or region. Keep the slash and trailing digits in your notes.
A search for HX6056/77 must not silently become HX6056/87. If only a similar code appears, treat it as a separate product until verified.

How to apply it

A family label describes the bristle design, while a manufacturer part number identifies a particular retail pack. For example, a six-pack and a differently numbered regional pack should remain separate records even if they use the same head family. Enter the entire code in reverse search.
