Crest Whitestrips expiration codes are typically printed on the box or individual pouches. The code usually consists of a series of letters and numbers indicating the manufacturing date, with the first two digits representing the year and the following digits indicating the month and day. For example, a code like "2103" would mean the product was made in March 2021. Always check for the expiration date to ensure the strips are effective.
