Autolink references validation is too strict

Hello, I’m using GitHub Enterprise Server 2.19.5 and my reference prefix is a single letter (W-), but when I try to add an autolink reference, I see: 

Reference prefix is too short (minimum is 3 characters) and Reference prefix must only contain letters, numbers, or -:/

Please consider relaxing the validation, especially around reference prefix length. Thanks!


HI @dannywils,

Thank you for being here! Although we don’t have a workaround at this time, we’ll pass this along to our product team. I can’t promise if or when this might be addressed but your feedback is in good hands!

Using Rally and the prefix is just 2 characters followed by a number. US<num>. We cannot create a prefix of US due to the above constraint. Also, we cannot add 10 autolinks US0, US1, US2 … US9 due to prefixes not allowing numbers. If either of these were changed then we would be able to use the autolinks feature with Rally.

The limit is too short for us, too. We’d like to use it for Clubhouse references (chXXXX) and Productboard (pbXXXX), but the 3-char limit blocks us.

We’re using Jetbrains YouTrack, and it’s task ids can be as short as X-1.

We are also using Rally, I thought an option would be to use the prefix RALLY- but the restriction is that it must be followed by only a number, thus RALLY-US1234 does not work.

Both of the restrictions are making it difficult to auto link with Rally.
Either allow US only as a prefix, or relax the ‘appended by a number’ restriction, the first being preferred.

For now resorted to using US- and asked developers to add the dash when copying the work number from Rally.
