It’s important that your musician business cards contain your contact information such as phone number, email address, and home address. Having this information will give potential customers the ability to contact you if they have any questions. Your telephone number should also include the area code and not just the city you live in. Having your mailing address on the card is optional, but it will help attract potential buyers to sign up for your newsletter or website. You can find websites that will print your cards for a very reasonable price.
