If you live in New York City or Philadelphia and hope to receive the iPhone 6S or iPhone 6S Plus by this Friday, you might be out of luck. Pope Francis is visiting to the United States later this week and extensive security measures could end up delaying shipments for users residing in both cities.

According to Mashable, UPS and FedEx—which Apple uses to distribute online orders in the United States—issued temporary service advisories for September 24 – 26. However, there is still hope. Apple Stores across New York and Philadelphia will reportedly have phones in stock, if you go by what Mashable is saying. For those who prefer to wait it out, UPS will not perform pickups or deliveries for the following ZIP codes:

New York, September 24-25

10001, 10007, 10017, 10021, 10022, 10023, 10029

Philadelphia September 25-26

19102, 19103, 19104, 19106, 19107, 19109, 19123, 19130, 19146, 19147

FedEx users can head over to their website to track changes in service.
