IAG is proposing to shut its 53 AMI stores and its remaining State store, and move its 350 staff to digital and contact centre roles.
About 65 management positions could also be disestablished, however, the company said it hoped to redeploy as many staff as possible.
IAG spokesman Kevin Hughes said the review reflected growing customer expectations for digital services, which had been accelerated by the Covid-19 pandemic.
"For several years, we've seen a decline in visits to our retail stores as customers increasingly look to engage with us over the phone, via email and through our online platforms and digital channels," he said.
