Frequently asked questions about accessing the NASC ePortal
Which devices can be used to access the NASC ePortal?
The NASC ePortal can be accessed via a web browser on Windows devices (computers, laptops and tablets), Apple Mac computers and laptops, Apple iOS devices (iPhones and iPads) and Android devices (phones and tablets).
Access is via a web browser, so you need to be connected to the internet. A Wi-Fi or 4G+ connection is preferred.
You should be using an up-to-date, supported operating system, otherwise your web browser may be out-of-date and may experience problems. The operating systems supported by their suppliers are Windows 10 - 11, MacOS 13.7+, iOS 17.7+ and Android 12+.
Go back to the NASC ePortal home pageWhich web browsers can be used?
The NASC ePortal will work on most up-to-date browsers, but some offer better performance than others.
On Windows, Chrome, Firefox and the latest version of Microsoft Edge (the new edition built on Chromium) are preferred. It is no longer possible to use Internet Explorer or the original edition of Microsoft Edge, which have been retired by Microsoft.
On an Apple Mac, iPhone or iPad, the default Safari browser works well, as does Chrome. Chrome is also recommended for Android devices.
You can upgrade your web browser or choose a new one here for free - it just takes a few minutes.
