The usual chaos.</p> <p>bharataddress handles parsing, formatting, validation, geocoding, address similarity, batch processing and DIGIPIN encoding. All offline. No API keys. No ML. 4.3MB total.</p> <p>62.5% exact match on a public 200-address gold set. Tested head to head against Shiprocket's 760MB TinyBERT NER model on the same test set. bharataddress wins on 6 of 9 fields. Fully reproducible.</p> <p>What you get:</p> <ul> <li>parse() turns messy address strings into structured JSON</li> <li>geocode() gives you lat/lng from pincode centroids for 16,400+ pincodes</li> <li>encode_digipin() generates India Post's new 10-char geo-code</li> <li>format() outputs India Post / single-line / shipping label styles</li> <li>validate() checks consistency and flags whether an address is deliverable</li> <li>address_similarity() gives you a 0-1 score for dedup</li> <li>parse_csv() and parse_dataframe() for bulk processing</li> <li>extract_state_from_gstin() pulls state from GST numbers</li> </ul> <p>pip install bharataddress<br> <a href="https://github.com/Neelagiri65/bharataddress" rel="noopener noreferrer">https://github.com/Neelagiri65/bharataddress</a></p> <p>100 tests.
