Payment Troubleshooting

Customer display doesn’t recognize tap/contactless payment.

  • On Square Register, confirm that you’ve pressed the “Charge” button to activate the customer display to accept contactless cards/phones. The LED indicators should light up when you tap the “Charge” button.

  • It is also possible that the contactless card or NFC-enabled phone is damaged or broken. In this case, ask your customer to present a different form of payment.

Chip cards aren’t recognized.

  • Ensure chip cards are inserted with the chip facing towards the buyer when the customer display is both docked and undocked.

  • If magstripe and contactless payments still work, the chip may be damaged. In this case, ask your customer to present a different form of payment.

  • It is also possible that, if magstripe cards and contactless payments still work, something may have damaged the chip card slot. If you think this is the case, contact Square Support.

Network Requirements

Protocol/Port Whitelisting

If you enforce restrictions on what protocols and ports that devices on your network can access, Square devices require the following protocols and their corresponding ports to be allowed through your firewall:

  • NTP. Note: This is critical for ensuring that the device has the correct time. Connectivity may fail due to certificate validity mismatches if the device time is wrong.

  • HTTPS (only port 443). Note: All traffic to Square servers is made over HTTPS.

The following ports are also used for network printers, but these do not require access to the internet:

  • UDP: 22222, 3289

  • TCP: 9100:9109

Domain Filtering

If you enforce restrictions on what domains can be accessed from within your network, Square devices require the following domains to be whitelisted.

HTTPS trafficAll subdomains of:

  • squareup.com

  • issquareup.com

  • squarecdn.com

  • cash.app

  • squarecloudservices.com

As well as the following FQDNs:

  • api.skyhookwireless.com

  • notify.bugsnag.com

  • sessions.bugsnag.com

  • azonaws.com

  • square.site

  • www.weebly.com

  • api.mapbox.com

NTP trafficNTP requires access to:

  • time.android.com

IP Addresses

Square’s IP address ranges are:

  • US: 74.122.184.0/21

  • Asia/Pacific: 103.31.216.0/22

  • Europe: 185.57.56.0/22

Square devices also rely on access to Amazon Web Services (AWS) and Google Cloud Platform (GCP). AWS IP ranges are published here, and Google is AS15169.

Note: Square devices have an internal firewall and an internal (domain, not IP) whitelist, and perform TLS certificate pinning on all Square endpoints, so you may consider the IP whitelisting on your side redundant depending on your purpose. It could make sense to just ensure Square devices can’t access any internal company IP addresses, and leave the rest of the internet open for Square’s on-device firewall and domain filter.
