Address data quality comes down to four properties: accuracy, completeness, consistency and currency. When all four hold, deliveries land, campaigns reach real people, and analytics can be trusted.
The four dimensions
- Accuracy — the address matches a real PAF record
- Completeness — no missing building, street or postcode
- Consistency — uniform formatting across systems
- Currency — reflects the latest PAF updates
Common problems
Free-text fields invite typos and abbreviations; merges and migrations create duplicates; and static lists drift out of date. Standardisation and verification fix these.

Frequently asked questions
What is address data quality?
Address data quality measures how accurate, complete, consistent and current your address records are. High-quality data matches real PAF addresses and is formatted consistently.
How do I improve address data quality?
Capture verified addresses at entry, standardise formatting, deduplicate using stable identifiers like UDPRN/UPRN, and re-verify periodically against current PAF data.
Why does address data quality matter?
Poor address data causes failed deliveries, wasted marketing spend, compliance risk and unreliable analytics — all of which clean data prevents.
