Can I set the build number in VSTS build

Question

When I create a new build definition then build number starts with 1. It gets increment with each build.

Can I set the initial build number instead it takes the default value (1)?

In the existing build definition can I bump the number, assume current build number is 1345, I want to add a offset of 1000 so that build number would be 2345?

Answer 1

Point of clarification: What you're talking about is the build ID, not the build number.

You can control the build number format as described in Shayki's answer.

However, the build id is a system-controlled unique identifier that you cannot change.

Answer 2

You can determine the build number format in the Options tab:
