How to Find the Address of a Business
See common business addresses.
If you have the business name: Search for the business name on Google or Bing to find the address on the business's website or directories like Yelp or Yellow Pages. Additionally, check with the Better Business Bureau as they may have information on the business and its address.
If you have the other party's telephone number: Use a paid or free online reverse phone lookup service, like Whitepages or Spokeo. Alternatively, if it is a landline number, contact the phone carrier to ask for the associated address, but note that some carriers may require legal documentation like a subpoena.
If the other party is a Corporation or LLC: LLCs and corporations must register with the state's regulatory agency, often called the Secretary of State, to operate. If your state lacks a Secretary of State, search for a "Division of Corporations" or "State Corporation Commission." The state's business registration database is frequently available online and can be searched using the business name to obtain the business address. (Ex: California SOS Business Search).
If you aren't sure what type of business the other party operates under: refer to this resource to learn more about business types.
If the other party is a Limited Partnership: Limited Partnerships are registered at the state level, possibly in a different department than Corporations/LLCs. Search online for where Limited Partnerships are registered in your state and request business address information from the relevant agency.
If the other party is a Sole Proprietorship or Partnership: For SP and Partnerships, registration is usually done at the county or city level. To find the business address, you can check with the clerk's office in the city or county where the business is located. Some clerk's offices may have business records available online for you to search, while others may require you to call and ask for assistance.
If the other party is an online business: To locate the address of an online business, check for a return address on any correspondence you've received. If there is no return address, the postage may have been printed from a postage meter. To get information on the owner of the postage meter, contact the USPS.
If the business is part of an association or chamber of commerce: contact the association to obtain the business’s address.
If the business has a post office box: You can request from the USPS the name, address, and telephone number of the holder of a post office box that is used for business purposes. Bring proof that the box is used for business purposes.
If I still can't find an address, how can I still demand payment?
To demand payment from someone whose address you can't find, you can send a demand letter electronically, but you'll need to include an address, such as your own. However, this method may not be reliable as the other party can dispute receiving it. If you plan to file a lawsuit, you'll need to locate the person or business to serve them the court paperwork.
