How to Number Company Assets

Numbering is the part of asset tagging that is cheapest to get right and most expensive to change. Once tags are fixed to five thousand items, the convention is effectively permanent.

Four rules that hold up

1. Fixed length. Pad with zeros — 0042, not 42 — so numbers sort correctly in every spreadsheet and system.
2. Never reuse. When an asset is disposed of, retire its number permanently.
3. Limit meaning. One or two prefix segments at most. Anything that can change should not be encoded.
4. Leave room. Size the digit count for several years of acquisitions, not for today's count.

What to encode in the prefix

Good prefix candidates are stable: site, campus, department or broad asset category. Poor candidates change constantly: assigned user, exact room, condition, supplier or model.

A worked example

A college with 1,800 assets across three departments allocates ranges per department in blocks of 2,000: ICT-0001 to ICT-1999, LAB-0001 to LAB-1999, ADM-0001 to ADM-1999. Each department can be counted independently, new items continue the sequence, and no renumbering is needed when a fourth department is added — it simply receives a new prefix.

Before you order tags

• Confirm the highest number currently in use, so a new batch continues rather than collides
• Fix the digit count and prefix segments in writing
• Check the longest possible number fits the tag size and any barcode you plan to include
• Agree who updates the register as tags are applied, and when
