On Silver Paw tags, the information is deep-engraved, material is actually removed from the very hard stainless steel. Much deeper than a stamp can make in other tags.

The tags themselves are made at New England Castings in Hiram, ME (see the process - click here).
The polishing and engraving is done in Brownfield, Maine.
