Business License - Arizona does not issue nor require a state business license, however, most city/town offices issue business licenses. Some may only require businesses that are based within their jurisdiction to obtain their license; others may require anyone conducting business within their city/town limits to obtain their license. There is not a "blanket state license" that allows you to "opt out" of obtaining any local licenses which may be required.
For questions about whether or not your business activity is subject to one or more business licenses, check with each
city/town office in which you plan to be based and/or conduct business.
