The short answer
This charge is from Zipcar, the hourly car-sharing service. It may appear as a clear 'ZIPCAR' descriptor, or as a cryptic string of letters and numbers representing an internal transaction ID.
Why the charge looks confusing
While many Zipcar charges clearly state the company name, specific billing events (like delayed toll processing, traffic citations, or membership renewals) can sometimes be passed through bank processors as a confusing alphanumeric string.
Zipcar often places a pre-authorization hold on your payment method when you reserve a car. This pending charge may look different from the final settled amount based on the actual time you used the vehicle and any miles driven over your daily limit.
- Sign in to your Zipcar online account and review to the 'Billing' section.
- Match the transaction date and exact dollar amount to your recent trips or membership fees.
- Check your email for automated receipts or notices regarding tolls and citations.
Why was I charged days after my trip?
Fees for tolls, parking tickets, or late returns are often processed by third parties and billed to your account weeks after the reservation.
What is this alphanumeric code on my statement?
Due to payment processing quirks, some Zipcar charges appear as internal tracking codes (e.g., MAY-I-Z...) rather than the company name. Cross-reference the amount in your Zipcar billing history.
