Tags provide specific identification and classification of AWS resources by associating them with descriptive metadata. A tag basically consists of a key and a value, both of which are defined by the user. Once defined, these tags can be used to filter when requesting specific resources.

Tagging Restrictions:

  • The following basic restrictions apply to tags:
  • Maximum number of tags per resource – 10
  • Maximum key length – 127 Unicode characters
  • Maximum value length – 255 Unicode characters
  • Tag keys and values are case sensitive
  • Tag keys must be unique per resource
  • Do not use the “aws:” prefix in your tag name or values because it is reserved for AWS use.
