ISO says that all gages must have a i.d. number.
No, it does not. I suspect your current system may, but ISO 900x does not.
ISO 9001; 4.11.2(b) states:
identify all inspection, measuring, and test equipment that can affect product quality, and calibrate and adjust them at prescribed intervals, or prior to use, against certified equipment having a known valid relationship to internationally or nationally recognized standards.
ISO 9001; 4.11.2(d) states:
identify inspection, measuring, and test equipment with suitable indicator or approved identification record to show the calibration status.
Key words: 'or approved identification record' and 'suitable indicator.'
Records are the key. If the gage is traceable to a record by a 'suitable indicator,' you should be OK. The suitable indicator is entirely up to your organization's best interest.
