There are other older threads on this question but people there are saying they got their number within 48 hours or within a few days. But I have applied for it and told them its urgent as I need it to get a job, but its been about 10 days and I'm still waiting for it. Their helpline puts me in a 15-20 minutes queue so I couldn't contact the department.
Does anyone know how long it take for IRD number to arrive after application through PostShop nowadays?
