How many phone numbers should I put on my business card?

One number is ideal, and two is the practical maximum. The goal is to make it obvious how to reach you, and every extra number adds a decision the other person has to make.

• List a single primary number if you can, so there is zero ambiguity about how to reach you.
• Two numbers, such as a mobile and an office line, only work if you genuinely answer both.
• Three or more numbers creates hesitation, and a prospect who is unsure which to call may not call at all.
• Label each number clearly, for example Mobile or Office, so the choice is easy.

Fewer, clearer options almost always beat a long list. Make the next step effortless.
