Frequently Asked Questions

Why You Might Want to Alter Your Company’s Address

If you are looking to start a new business venture, whether online or offline, you may want to consider changing your business address. While most people think of changing addresses as being necessary to avoid unwanted visitors, there are many benefits to doing so. Here are just a few things you might find out about why you may want to change your business address:

1. Avoid Unwanted Visitors

While it is important to make sure that your business address is correct and updated, it is equally important to ensure that it is not publicly accessible. If someone sees your business address – even if it is incorrect – they may assume that you operate from that location, and thus show up at your doorstep without warning.

2. Save Money on Mailing Services

Mailing lists are expensive. They can cost anywhere from $10-$100+ per month depending on how much data you require. However, if you do not wish to receive unsolicited advertising or marketing materials, then it makes sense to change your business address to one that does not attract such attention.

3. Improve Brand Image

Having a professionally designed logo and web presence is essential to building brand recognition among your target audience. By choosing a different address, you can help improve your brand image in a number of ways. For example, if your current address contains a typo or outdated information, potential customers may associate your business with the wrong impression.

How to Change a Business’ Registered Address?
