What you're looking for is called "geocoding": Converting an address to GeoCoordinate.

As was mentioned before you can use Google and Bing on WP7 to achieve that. On windows phone 8 Geocoding and Reverse Geocoding are supported as part of the framework. You can read an overview to GeoCoding at this Nokia intro article (under "Geocoding") and a more comprehensive overview at this other Nokia article.

Here's an example of Geocoding converting from an address to coordinates:

private void Maps_GeoCoding(object sender, RoutedEventArgs e)
{
    GeocodeQuery query = new GeocodeQuery()
    {
        GeoCoordinate = new GeoCoordinate(0, 0),
        SearchTerm = "Ferry Building, San-Francisco"
    };
     query.QueryCompleted += query_QueryCompleted;
    query.QueryAsync();
}

void query_QueryCompleted(object sender, QueryCompletedEventArgs> e)
{
    StringBuilder sb = new StringBuilder();
    sb.AppendLine("Ferry Building Geocoding results...");
    foreach (var item in e.Result)
    {
        sb.AppendLine(item.GeoCoordinate.ToString());
        sb.AppendLine(item.Information.Name);
        sb.AppendLine(item.Information.Description);
        sb.AppendLine(item.Information.Address.BuildingFloor);
        sb.AppendLine(item.Information.Address.BuildingName);
        sb.AppendLine(item.Information.Address.BuildingRoom);
        sb.AppendLine(item.Information.Address.BuildingZone);
        sb.AppendLine(item.Information.Address.City);
        sb.AppendLine(item.Information.Address.Continent);
        sb.AppendLine(item.Information.Address.Country);
        sb.AppendLine(item.Information.Address.CountryCode);
        sb.AppendLine(item.Information.Address.County);
        sb.AppendLine(item.Information.Address.District);
        sb.AppendLine(item.Information.Address.HouseNumber);
        sb.AppendLine(item.Information.Address.Neighborhood);
        sb.AppendLine(item.Information.Address.PostalCode);
        sb.AppendLine(item.Information.Address.Province);
        sb.AppendLine(item.Information.Address.State);
        sb.AppendLine(item.Information.Address.StateCode);
        sb.AppendLine(item.Information.Address.Street);
        sb.AppendLine(item.Information.Address.Township);
    }
    MessageBox.Show(sb.ToString());
}

When I run this code snippet on my WP8 I get the following messagebox:
