}Notes
- Wording: OCA sends no status codes, so its Spanish state names are mapped (
Entregadodelivered,Visita a Domicilio en Cursoout for delivery,Devuelto al Remitentereturned,No entregadoexception). A reason other than "Sin Motivo" is appended to the description in brackets. - Delivery time:
deliveredAtis theEntregadoscan, not the laterAcuse digitalizado(scan of the signed proof). - Time zone: scan times are Argentina time (UTC-3 all year).
- How it is queried: OCA's e-Pak tracking web service called with its customer fields empty; no captcha is involved.
