The key min_age=* is used when the visitors of an amenity, a shop, venue, building or any other kind of place, need to have a minimum age. It is the counterpart to max_age=*.


The age in years is used as value. If just a number is given, this will be interpreted as years. The dot (.) can be used as decimal mark.

If you want to express months or weeks, add " months" or " weeks" to the numeric value (singular for 1 week or month, plural otherwise). If necessary, years, months and weeks can be combined. If years are combined with months and/or weeks, please append " years" to the number of years.



Until July 2014 the two keys min_age=* and minage=* coexisted. Both had a wiki-page with similar descriptions.

After a discussion on the @tagging mailinglist (see [1]) these were merged into min_age=*, especially for better readability (-age is a common suffix, so similar words – like milage, mirage or menage – exist, what makes it harder to read, particularly for non-native English speakers).
