A charge with a descriptor like "200076-3555Walnut-GMP- 720-5043620 CO" is most likely a parking fee processed by Parkwell for parking at the 3555 Walnut Street lot in Denver, Colorado. The descriptor embeds the facility address (3555 Walnut) and Parkwell’s main contact phone number (720‑504‑3620), which appears consistently across Parkwell‑managed facilities. Charges may represent hourly or daily parking, evening or event parking, or a monthly parking pass billed to a card on file, and may be created either by paying at the lot or reserving online through a partner platform.([parkchirp.com](https://parkchirp.com/facilities/3555-walnut-street-lot/?utm_source=openai))
