GEOCODING AUDIT WORKSHEET Yenra | October 11, 2026 Guide: https://yenra.com/geocoding/ Service: https://geocoding.geo.census.gov/geocoder/ Documentation: https://geocoding.geo.census.gov/geocoder/Geocoding_Services_API.html Purpose: document one small geocoding job. Keep original records and unresolved cases. Use public addresses for practice; establish permission and review service handling terms before uploading personal addresses. JOB Question and required location detail: Provider, country coverage, and service operation: Request date: Benchmark/reference dataset: Geography vintage (if requesting containing geographies): Coordinate reference information and units: Permitted final map detail (points or aggregated areas): PER-RECORD TEMPLATE -- repeat for each stable record ID Record ID: Original address: Cleaned address and reason for any change: Provider's matched address: Provider result type / candidates / match status: Longitude (X): Latitude (Y): Coordinate units: Independent evidence checked: Review decision: accepted / ambiguous / unmatched / needs correction Reason, reviewer, and date: Retry history: PUBLIC EXAMPLE -- checked October 11, 2026 Input: 4600 Silver Hill Rd, Washington, DC 20233 Benchmark: Public_AR_Current Matched address: 4600 SILVER HILL RD, WASHINGTON, DC, 20233 Longitude X: -76.92836638093 Latitude Y: 38.84505589808 Units: decimal degrees. The Census result estimates a location along an address range. It is not a surveyed entrance. Current benchmarks change; retain the dated response. For importing, choose longitude as X and latitude as Y, check reference information, then inspect the expected region. Never infer accuracy from the count of decimal places. FICTIONAL AUDIT EXERCISE 20 input records: 17 accepted, 2 ambiguous, 1 unmatched. Accepted percentage = 17 / 20 x 100 = 85%. Counting ambiguous candidates as matches gives 19 / 20 = 95%, a different measure. State which measure you report. Retain all 20 original records. DELIVERY CHECK [ ] IDs preserve the join to original records; duplicates are intentional. [ ] Postal codes and IDs retain leading zeros where applicable. [ ] Longitude/latitude order, signs, and reference information checked. [ ] Provider matching is distinguished from human acceptance. [ ] All unresolved rows remain visible in a review list. [ ] Data versions, dates, decisions, and original responses retained. [ ] Public output uses the approved level of location detail.
