Can anybody help me? It seems I used to do this on-line in the past without too much trouble, but today the website is super slow and glitchy and it just isn’t giving me what I need. If anybody has a link to a complete postal chart, domestic U.S. and International, I’d appreciate it. I can usually navigate these better than a website. Many thanks.
