To check your GCash limit, open the app and go to the 'Profile' section. Here, you can view your current limits under 'Limits'. If you want to increase your limit, you’ll need to complete the verification process. This usually involves submitting a valid ID and a selfie for identity verification. Once verified, your limits may be adjusted based on GCash's evaluation, so keep an eye on any notifications from the app for updates on your new limits.
