Do I need to alert Brex about my travel plans?

No need! We understand that operating a business can take you around the globe–and in fact, we expect it to.. That’s why we’ve designed Brex cards to be used from anywhere, without the need to inform us of your plans. 

Your transactions won’t be blocked just because it’s taking place in a new or international location, as long as it falls within the restrictions mentioned here: Where can't I transact with my Brex card?. So feel free to keep spending on your Brex card during your travels.
