San Pedro Electric Sign Company

Every one of the 100 sign making listings for Los Angeles comes with a phone number on file, and 97 of them list a website too, so you can call or click through before you ever leave the house. That kind of coverage means you can line up two or three shops in one sitting and compare without hunting for contact details first. Zip codes like 90019, 90022, 91304, 91311, and 91406 each carry four listings, giving those pockets of the city a denser cluster to choose from, while spots like 90006, 90007, and 90028 hold a handful more.

Paid placement hasn't launched in this category yet, so nothing here carries a Sponsored label, and every listing is showing up labeled and identifiable the same way regardless of budget. That's worth knowing as you scroll: what you're looking at reflects available data, not a bidding war. If you own or manage one of these sign shops and see a phone number that's outdated or a website field sitting empty, you can claim the listing and correct it, which saves the next person searching Los Angeles sign makers a dead-end call.
